Continuing maintenance

[ItzSwirlz]

I originally made this as part of a mid-year project for my freshman year of CS. Other GTK stock market apps have actually been archived or are discontinued, to my knowledge (like Markets).

Although Stocks and business isn't my main thing, stox is special, and although my Gtk knnowledge/UI dev isn't really the best, I'd love to see this project continue to flourish.

That being said, PRs are welcome, but don't expect me to have this as my #1 thing other than school :)
